The Effects Of Atomic Oxygen On Patch Antenna Performance And Lifetime, Max J. Barta
The Effects Of Atomic Oxygen On Patch Antenna Performance And Lifetime, Max J. Barta
Master's Theses
The space environment is a volatile and challenging place for satellites to survive in. For Low Earth Orbiting (LEO) satellites, atomic oxygen (AO) is a constant corrosive effect that degrades the outer surface of satellites over long durations. Atomic oxygen exists in the atmosphere between 180 and 675 km and has a relatively high energy at 4.5 eV, which allows AO to break molecular bonds in materials on the surfaces of spacecraft. As the number and complexity of CubeSat missions increase, there is an increased risk that AO degradation on commercial off the shelf parts (COTS), such as antenna, could …
